Yeah, like you're connected with an ethernet cable.
I get a little better numbers from my office - on westhash, not f2:
PING westhash.com (141.101.127.76): 56 data bytes

Guys, guys, you are not pinging our stratum servers but CloudFlare's proxy servers for our web page which will always be close to you since CloudFlare has globally distributed infrastructure. But web servers has nothing to do with mining, you have to ping stratum servers to find your ping time. We have ping disabled on our stratum servers, but you can ping the endpoints of our provider's datacenters:
"ping speedtest.ams01.softlayer.com" for NiceHash
"ping speedtest.sea01.softlayer.com" for WestHash
this will give you ping results, relevant for miners your (should be below 100ms for optimal results) - of course you should ping from the location of your miners.
f2pool stratum address is stratum.f2pool.com
"ping stratum.f2pool.com" will give you ping results for f2pool connection.
